    Why you should care about Mapping of the Fruit Fly’s Brain?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Brain mapping of fruit flies and its applications

    Why in the News?

    Researcher have successfully mapped the entire brain of an adult fruit fly, marking the first time researchers have created such a detailed map of an adult animal’s brain.

    How Was the Fruit Fly Brain Mapped?

    • The process of mapping Fruit Flies (Drosophila melanogaster) brain began in 2013.
    • Scientists dunked the brain of an adult fruit fly in a chemical bath, hardening it into a solid block.
    • This process involved 7,050 sections of the brain and produced 21 million photos to map the entire brain.
    • The first high-resolution image of the brain was created more than a decade after the work started.

    Key findings

    • Scientists identified more than 50 million connections between 139,000 neurons (brain nerve cells).
    • They classified the cells into 8,453 distinct types, making it the largest catalogue of cell types in any brain.
    • The research gave insights into how different types of cells function and how the fruit fly’s eyes process motion and color.
    • A group of “hub neurons” was discovered, which may help speed up information flow.

    Significance of the Work

    • Although the human brain is more complex, the logic of how neurons communicate is similar between fruit flies and humans.
    • Fruit flies are a valuable model system for neuroscience. Their brains solve many of the same problems that human brains do.
    • It could help in understanding and treat mental health conditions like Parkinson’s and depression.
    • The mapping of the fruit fly’s brain raises hopes that scientists will eventually be able to map the entire human brain.

    What are Psychedelic Drugs?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Psychedelic Drugs

    Why in the News?

    Researchers from the Tata Institute of Fundamental Research (TIFR) in collaboration with researchers from Cornell, Yale, and Columbia has uncovered how a psychedelic drug interacts with the brain to alleviate anxiety.

    About Psychedelic Drugs

    • Psychedelic drugs are a class of psychoactive substances that alter perception, mood, and cognitive processes. 
    • These drugs often induce hallucinations, altered states of consciousness, and enhanced sensory experiences.
    • They are typically associated with spiritual experiences and have historically been linked with counterculture movements, but they are now being studied for their potential in medical therapies.
    • Examples of Psychedelic Drugs:
      • LSD (Lysergic acid diethylamide): Known for causing intense visual hallucinations and altering thoughts, it is one of the most potent psychedelics.
      • Psilocybin: The active compound found in magic mushrooms, known for creating visual and auditory hallucinations, as well as a deep sense of connection to the environment.
      • MDMA (3,4-methylenedioxymethamphetamine): Often associated with recreational use, but is also being researched for its therapeutic potential, especially in treating PTSD.
      • DMT (Dimethyltryptamine): Produces powerful, short-lived hallucinatory experiences, sometimes referred to as the “spirit molecule.”
      • Mescaline: Found in the peyote cactus, mescaline induces hallucinations and altered states of reality.

    How do they work?

    Psychedelics primarily affect the brain by interacting with the serotonin system, a network of neurotransmitters involved in regulating mood, perception, and cognition.

    • Serotonin Receptors: Psychedelics like LSD and psilocybin bind to 5-HT2A receptors, a type of serotonin receptor. This interaction leads to altered perception, enhanced mood, and hallucinations.
    • Brain Connectivity: They increase communication between different regions of the brain, breaking down normal patterns of activity. This leads to heightened creativity, altered sensory experiences, and a sense of connectedness.

    How Psychedelics hold promise for treating Anxiety and Depression?

    • Resetting Neural Circuits: Psychedelics may “reset” dysfunctional brain circuits, helping treat mood disorders.
    • Reduced Anxiety: They reduce overthinking by dampening activity in the brain’s default mode network.
    • Emotional Release: Patients experience emotional breakthroughs during psychedelic therapy sessions.
    • Neuroplasticity: Psychedelics may promote adaptive brain connections, aiding in recovery from chronic stress and depression.

    What are their Applications?

    • Medical Diagnostics: FNDs are used for high-resolution imaging and tracking cells over extended periods due to their non-toxic nature.
    • Temperature Sensing: FNDs can measure temperatures at the microscale, making them useful for scientific experiments.
    • Correlative Microscopy: Their fluorescent properties make them ideal for combining different types of imaging techniques.
    • Sensor Technologies: Due to their sensitivity to acceleration and electric fields, FNDs can be used in industry sensors and gyroscopes for rotation sensing.

    F&O: How will Sebi’s new rules affect traders and brokers?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: FandO Trading

    Why in the News?

    SEBI has introduced a six-step framework to protect investors and curb speculative trading, specifically targeting futures and options (F&O) trading by reducing volumes on expiry days and limiting retail participation.

    What are the Future and Options (F&O)?

    • Futures are contracts to buy or sell an asset (like stocks, indexes, or commodities) at a predetermined price on a future date.
    • Options give the right, but not the obligation, to buy or sell an asset at a set price before a certain date.

    SEBI’s Six-Step F&O Framework (Effective November 2024 – April 2025):

    In response to concerns about rising speculative trading, SEBI has outlined six key measures aimed at reducing retail interest in F&O trading:

    1. Upfront collection of options premiums
    2. Intraday monitoring of position limits
    3. Removing calendar spread benefits on expiry day
    4. Increasing the contract size for index derivatives
    5. Rationalizing weekly index derivatives to one benchmark per exchange
    6. Enhancing margin requirements on options expiry days

    Key Changes for Retail Investors:

    • Upfront Collection of Options Premiums: Retail investors must now pay the full premium upfront, limiting their ability to use high leverage in options trading.
    • Increased Contract Size: The minimum contract size for index derivatives is raised to ₹15 lakhs, reducing speculative retail participation by making it costlier to enter.
    • Rationalization of Weekly Expiries: Only one benchmark index per exchange can have weekly expiries, lowering speculative trading opportunities and intraday volatility.
    • Removal of Calendar Spread Benefits: Calendar spreads are no longer allowed on expiry days, discouraging aggressive trading strategies.

    Impact on Brokers and Revenue:

    • Decline in Trading Volumes: Brokers reliant on F&O trading will see reduced volumes due to fewer retail participants and higher barriers to entry.
    • Revenue Drop in Options Trading: Firms like Zerodha may face a 30-50% revenue drop as retail participation in options decreases.
    • Shift to Equity Trading: Retail investors may move towards equity trading, causing brokers to adapt their offerings.
    • Adaptation for Brokers: Brokers with a balanced mix of cash and derivatives will be less impacted, while those focused on F&O need to shift strategies.

    PYQ:

    [2021] With reference to India, consider the following statements:​

    1. Retail investors through demat account can invest in ‘Treasury Bills’ and ‘Government of India Debt Bonds’ in primary market.​
